Abstract :
We have developed a millimeter wave pulsed electron spin resonance (ESR) spectrometer by using a high power radiation source gyrotron. As the first, we introduce a high power millimeter wave pulse forming system by using light controlled semiconductor shutters. Nanoseconds millimeter wave pulses (15 ns and 27 ns) were realized with the microseconds order arbitrary delay time tau.
